Whose Poop is This, Anyway?

So this isn't poop, but it does appear that a spider or caterpillar had sudden, explosive diarrhea of the silk spinnerets!

It's difficult to see, but along the left side is a single strand floating about with a smaller blob on its end.

I was out performing my part of fetch with Delia, and saw something white a fluttery land out by the fence line. It looked like a piece of paper... the kind that floats out of a fire, so I had to investigate immediately. Turns out it was a big ol' blob of silk. Nature is lovely and strange.
